  Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. In addition, not all the combinations of features described in the embodiments are essential for the solving means of the invention.

  FIG. 1 is a schematic diagram for explaining the outline of the electronic lock management system according to the first embodiment. The electronic lock management system 10 is constructed with the server device 100, the administrator terminal 200, the portable terminal 300 (300a to i in the figure), and the electronic lock device 400 (400A to C in the figure) as main components. The administrator terminal 200 is connected to the server device 100 via a LAN. The mobile terminal 300 can be connected to the server device 100 via the Internet. On the other hand, the electronic lock device 400 is a stand-alone electronic lock device that is not connected to a network.

  The electronic lock management system 10 can be applied to, for example, disaster prevention stockpiling warehouses, shelters, and the like. In this embodiment, the case where the electronic lock management system 10 is applied to a disaster prevention storage warehouse will be described as an example.

  The server device 100 plays a role as an electronic lock management device that manages the locking and unlocking of the electronic lock device 400. The server device 100 collectively manages unlocking information for unlocking a lock mechanism of an electronic lock device attached to a door of a disaster prevention storage warehouse installed in a plurality of specific areas. Here, the “specific area” is an area set in advance as an area managed by the server device 100. In the following description, the specific area may be referred to as a “management area”.

  FIG. 1 shows areas A, B, and C as different management areas. In the present embodiment, each management area is, for example, an area in units of municipalities. Each management area includes a plurality of disaster prevention stockpiling warehouses that are properties to be managed. In the following description, a property that is installed in a management area and is subject to management of locking and unlocking may be referred to as a “managed property”.

  In FIG. 1, the disaster prevention stockpiling warehouse A <b> 1 is representatively shown in a region A among a plurality of managed properties installed. An electronic lock device 400A is installed on the door of the disaster prevention storage warehouse A1. In addition, in the area B, a disaster prevention storage warehouse B1 is shown as a representative among a plurality of management properties installed. An electronic lock device 400B is installed at the door of the disaster prevention storage warehouse B1. And in area C, disaster prevention storage warehouse C1 is shown as a representative among a plurality of management properties installed. An electronic lock device 400C is installed at the door of the disaster prevention storage warehouse C1.

  In the server device 100, one or more portable terminals associated with the electronic lock device of the managed property installed in the management area are registered in advance. In other words, the server device 100 stores a plurality of portable terminals in association with the electronic lock device installed in each disaster prevention storage warehouse. These portable terminals are used as electronic key terminals in an emergency. In FIG. 1, portable terminals 300a, 300b, and 300c are associated with the electronic lock device 400A. In addition, portable terminals 300d, 300e, and 300f are associated with the electronic lock device 400B. The mobile terminals 300g, 300h, and 300i are associated with the electronic lock device 400C.

  In FIG. 1, in area A, a registrant a who is the owner of the mobile terminal 300a, a registrant b who is the owner of the mobile terminal 300b, and a registrant c who is the owner of the mobile terminal 300c are shown. . In the region B, a registrant d who is the owner of the mobile terminal 300d, a registrant e who is the owner of the mobile terminal 300e, and a registrant f who is the owner of the mobile terminal 300f are shown. In area C, a registrant g who is the owner of the mobile terminal 300g, a registrant h who is the owner of the mobile terminal 300h, and a registrant i who is the owner of the mobile terminal 300i are shown. In the present embodiment, the registrants a to i are, for example, local government employees in the respective areas.

  As described above, the server apparatus 100 stores in advance, as a registration list, information on the management area, the management property, and the mobile terminal that are associated with each other. Details of the registration list will be described later.

  It is preferable that the server apparatus 100 is installed in a place not included in any management area. The server apparatus 100 receives disaster information related to a disaster. The disaster information is, for example, an emergency signal transmitted from an administrative organization. In this embodiment, the emergency signal is an emergency earthquake bulletin transmitted from the Japan Meteorological Agency. In addition, the server apparatus 100 can acquire a signal including various information issued from a public organization in an emergency as an emergency signal. The emergency signal may be a signal including a warning and a forecast regarding a natural disaster such as a tsunami, an eruption, a pyroclastic flow, and a debris flow. Further, it may be a signal including information on an evacuation order and an evacuation recommendation announced by the local government.

  The disaster information may be an input signal from the administrator terminal 200 by an authorized administrator. In the present embodiment, the administrator is, for example, a disaster prevention person in a building where the server apparatus 100 is installed. In the present embodiment, when the administrator obtains information on the occurrence of a disaster from an information source such as a television or radio, the server device 100 sends a disaster occurrence notification signal for notifying the occurrence of a disaster by operating the administrator terminal 200. Send to. The disaster occurrence notification signal includes information on a management area estimated by the administrator that a disaster has occurred. The server apparatus 100 acquires a disaster occurrence notification signal as disaster information.

  In the present embodiment, when receiving any of the disaster information, the server device 100 transmits an emergency key ID for unlocking the electronic lock of the managed property in the management area to a specific mobile terminal. Here, the “emergency key ID” is an authentication ID for unlocking the electronic lock used in an emergency such as a disaster. In the present embodiment, the expiry date is determined in advance for the emergency key ID. For this reason, after the registrant receives the emergency key ID transmitted from the server device 100 and a predetermined time has elapsed, the registrant cannot unlock the disaster prevention storage warehouse with the emergency key ID.

  The electronic lock device 400 reads the authentication ID from the mobile terminal 300. The electronic lock device 400 collates the read authentication ID with previously stored authentication data. As a result of the collation, when the authentication ID matches the authentication data, the electronic lock device 400 releases the lock.

  The electronic lock device 400 according to the present embodiment stores emergency authentication data for authenticating an electronic key in an emergency in advance, in addition to authentication data for authenticating an electronic key during normal times.

  In the present embodiment, the emergency key ID and the emergency authentication data are updated by the administrator every time the server device 100 receives disaster information. In the present embodiment, the emergency key ID stored in advance in the storage unit of the server device 100 is rewritten from the administrator terminal 200 to a new emergency key ID via the network. In this embodiment, emergency authentication data stored in advance in an electronic lock device installed in each managed property is updated by a direct input operation by an administrator.

  Here, it should be noted that the disaster information includes misinformation. The emergency signal is a warning signal related to life, so it is often sent positively if any danger is predicted. For example, an emergency earthquake warning is sent even though an earthquake does not actually occur. May be. The disaster occurrence notification signal is sent by the administrator based on information obtained on a television or the like. However, since the manager is in a remote place away from the management area, the damage scale at the site cannot be fully understood. For this reason, even though the damage scale is actually relatively small, it may be transmitted.

  Electronic lock devices often have a function of protecting property. For example, if an electronic lock device in a stockpiling warehouse is unlocked even when it is falsely reported, it may be exposed to looting. Therefore, regarding “unlocking”, the actual occurrence of disaster should be judged more carefully. Therefore, in this embodiment, the emergency key ID is transmitted to the registrant associated with the managed property instead of being automatically unlocked only by the disaster information, and the registrant is based on the disaster situation at the site. A configuration that can determine whether unlocking is necessary or not is adopted. In this way, by interposing the judgment of the registrant at the site where the managed property is installed, it is possible to avoid unlocking the electronic lock device 400 even though no disaster has occurred. it can. Below, the electronic lock management system 10 concerning this embodiment is demonstrated in detail using figures.

  FIG. 2 is a block diagram illustrating the configuration of the server device. The server apparatus 100 includes a control unit 102 configured from, for example, a CPU, a network connection unit 104 serving as a network interface, and a storage unit 106 configured from, for example, a hard disk drive. The control unit 102 includes a memory 103 composed of a nonvolatile memory such as a flash memory.

  The control unit 102 comprehensively controls the operation of the components of the server device 100. The memory 103 stores an electronic lock management program as an application program for controlling the operation of the server device 100 in order to manage the electronic lock in the electronic lock management system 10. The control unit 102 calls and executes an electronic lock management program from the memory 103.

  The network connection unit 104 is connected to the LAN and enables the server device 100 to communicate with the administrator terminal 200. In addition, the network connection unit 104 connects to the Internet and enables the server device 100 to communicate with the mobile terminal 300. The control unit 102 and the network connection unit 104 function together to play a role as an information acquisition unit that acquires disaster information related to a disaster.

  The storage unit 106 serves as a registration unit in the present embodiment. The storage unit 106 stores a registration list in advance. The registration list includes managed area information, which is managed area information, managed property information, which is managed property information included in the managed area, and registered terminal information, which is mobile terminal information associated with each managed property. It is. In the registration list, the management area information, the management property information, and the registration terminal information are associated with each other. The registration list is stored in the storage unit 106 from the administrator terminal 200 via the LAN.

  The storage unit 106 stores a history list including the history of unlocking and locking of the electronic lock of the electronic lock device installed in the managed property. In the history list, information on the execution time of unlocking and unlocking of each electronic lock device, information on the mobile terminal that has performed unlocking, and the like are recorded.

  The control unit 102 and the network connection unit 104 function together to serve as a state acquisition unit that acquires the state of the mobile terminal. In this embodiment, a state acquisition part acquires the location information regarding the location of the said portable terminal as a state of a portable terminal. In the following description, the location information of the mobile terminal may be referred to as “terminal location information”. In the present embodiment, the terminal location information is latitude and longitude values.

  The control unit 102 and the network connection unit 104 function together and play a role as a transmission unit. When the information acquisition unit acquires disaster information, the transmission unit transmits an emergency key ID for unlocking the target disaster prevention storage warehouse to at least one of the mobile terminals registered in the registration unit.

  Furthermore, the control unit 102 plays a role as a determination unit. The determination unit compares the terminal position information acquired by the state acquisition unit with the installation position of the target disaster prevention storage warehouse, and determines to which portable terminal the emergency key ID is transmitted. In this embodiment, a determination part determines the portable terminal nearest to the installation position of the target disaster prevention storage warehouse as a transmission destination of emergency key ID.

  Specifically, the determination unit calculates a distance between the disaster prevention storage warehouse and the mobile terminal using a known calculation method from the latitude and longitude values of the target disaster prevention storage warehouse and the latitude and longitude values of the mobile terminal. To do. A determination part calculates the said distance with respect to each of the portable terminal linked | related with the target disaster prevention storage warehouse. And a determination part specifies each portable terminal nearest to the said disaster prevention storage warehouse by comparing each of the calculated distance, and determines as a transmission destination of emergency key ID.

  The transmission unit transmits the emergency key ID to the mobile terminal determined by the determination unit as the transmission destination of the emergency key ID. Specifically, a transmission part transmits emergency key ID which unlocks the electronic lock of the target disaster prevention storage warehouse to the said portable terminal by an email.

  When the server apparatus 100 receives the disaster information, the server apparatus 100 starts an emergency key ID transmission processing operation for unlocking the electronic lock installed in the managed property. Hereinafter, the operation of transmitting the emergency key ID by the server device 100 when the earthquake early warning from the Japan Meteorological Agency is received will be described more specifically.

  The control unit 102 analyzes the earthquake early warning obtained from the Japan Meteorological Agency, and recognizes the disaster prediction area included in the earthquake early warning. Here, the “damaged predicted area” is an area that is predicted to have a seismic intensity of 4 or more in the earthquake early warning. The control unit 102 determines whether the authorized disaster prediction area includes a management area registered in the registration list.

  When the control unit 102 determines that the management area registered in the registration list is included in the disaster prediction area, the control unit 102 selects a mobile terminal registered in association with the disaster prevention storage warehouse installed in the management area. Candidate for transmission of emergency key ID. In the following description, a management area included in a disaster prediction area may be referred to as a “damage prediction management area”.

  The server device 100 requests all mobile terminals in the disaster prediction management area to transmit terminal location information via the Internet. Each mobile terminal that has received a request for terminal location information from the server device 100 transmits its own terminal location information to the server device 100. The control unit 102 stores the terminal position information acquired from each mobile terminal in the storage unit 106 in association with the identification ID of the mobile terminal. Here, the “identification ID” is an ID unique to the mobile terminal such as a device ID.

  The control unit 102 specifies the mobile terminal closest to the target disaster prevention storage warehouse from the location information of the disaster prevention storage warehouse installed in the management area registered in the registration list and the terminal location information. And the control part 102 transmits emergency key ID of the said disaster prevention storage warehouse to the specified portable terminal. If it demonstrates concretely with reference to FIG. 1, the control part 102 will each of disaster prevention stockpiling warehouse A1 and each of the location information of disaster prevention stockpiling warehouse A1 and each terminal location information of portable terminal 300a, 300b, and 300c. Calculate the distance of the mobile terminal. And the control part 102 compares the calculated distance with each other, and specifies the portable terminal nearest to the disaster prevention stockpiling warehouse A1. In FIG. 1, the control part 102 specifies the portable terminal 300a as a portable terminal nearest to the disaster prevention storage warehouse A1. The control unit 102 transmits the emergency key ID of the disaster prevention storage warehouse A1 to the mobile terminal 300a via the network connection unit 104.

  The registrant a of the mobile terminal 300a that has received the emergency key ID from the server device 100 grasps the scale of the disaster at the site where the disaster prevention storage warehouse A1 is installed, and determines whether or not to unlock the disaster prevention storage warehouse A1. decide. That is, when the registrant a determines that the damage caused by the disaster is minor, the registrant a does not unlock the disaster prevention storage warehouse A1. On the other hand, when the registrant a determines that the damage caused by the disaster is enormous, the registrant a unlocks the disaster prevention storage warehouse A1. In this way, the registrant at the site confirms the scale of damage in the vicinity of the managed property and determines whether to unlock the managed property. Even if this is the case, unnecessary unlocking can be prevented.

  FIG. 3 is a diagram illustrating an example of a registration list. Specifically, this figure shows a registration list stored in advance in the server apparatus 100 described with reference to FIG.

  A plurality of management areas are registered in the server device 100. One or more managed properties are registered in each of the plurality of managed areas. One or more portable terminals are associated with each managed property and registered in the server device 100. In the example of the registration list shown in this figure, managed property information and registered terminal information are collected and listed for each management area.

  FIG. 3 shows a registration list for three management areas “area A”, “area B”, and “area C” as management area information that is information of the registered management area. In addition, it is shown that three managed properties are registered in each of the management areas “Area A”, “Area B”, and “Area C”. For example, “disaster prevention storage warehouse A1”, “disaster prevention storage warehouse A2”, and “disaster prevention storage warehouse A3” are shown as managed property information of “region A”.

  “Longitude xx.xxx latitude yyy.yyyy” is indicated as position information of the managed property “disaster prevention storage warehouse A1”. “Longitude yy.yyyy latitude zzz.zzz” is shown as position information of the managed property “disaster prevention storage warehouse A2.” In addition, “longitude zz.zzzz latitude xxx.xxxx” is indicated as position information of the managed property “disaster prevention storage warehouse A3”.

  FIG. 3 shows that a plurality of portable terminals are associated with each of the three managed properties and registered. As registered terminal information, an identification ID and a mail address of the mobile terminal are shown. In this figure, for example, identification IDs “OOXXXXX”, “□□□□□□□□”, and “△” of the mobile terminal registered in association with “disaster storage warehouse A1” are displayed. "△△△△△△△" is shown. And the mail address of each portable terminal is shown.

  FIG. 4 is a block diagram illustrating the configuration of the administrator terminal. The administrator terminal 200 includes a control unit 202 configured by, for example, a CPU, a network connection unit 204 that is a network interface, a display unit 206 configured by, for example, a liquid crystal display, and an operation unit 208 configured by, for example, a keyboard and a mouse. . The control unit 202 includes a memory 203 composed of a nonvolatile memory such as a flash memory.

  The control unit 202 comprehensively controls the operation of the components of the administrator terminal 200. The memory 203 stores a disaster occurrence notification program, which is an application program for an administrator to designate a management area estimated that a disaster has occurred and notify the server apparatus 100 of the disaster.

  The network connection unit 204 is connected to the LAN and enables the administrator terminal 200 to communicate with the server device 100. The display unit 206 displays a setting screen and a selection screen. The operation unit 208 receives input of various information from the administrator.

  When the administrator acquires information on the occurrence of an earthquake from an information source such as a television or radio, the administrator activates a disaster occurrence notification program on the administrator terminal 200. Upon receiving an instruction to start the disaster occurrence notification program from the administrator, the control unit 202 calls the disaster occurrence notification program from the memory 203 and executes it. The control unit 202 displays a designated operation screen for controlling the disaster occurrence notification program stored in the memory 203 on the display unit 206.

  The administrator operates the operation unit 208 and designates a management area where it is estimated that a disaster has occurred from the designation operation screen displayed on the display unit 206. The control unit 202 receives a designated input of the management area from the administrator, and transmits a disaster occurrence notification signal corresponding to the designated content to the server device 100.

  In this embodiment, the administrator updates the emergency key ID stored in advance in the server device 100 by using the administrator terminal 200 every time the server device 100 receives disaster information. For example, the administrator updates the emergency key ID to a new emergency key ID three days after the disaster occurs.

  And the control part 202 transmits new emergency key ID to the server apparatus 100 via LAN. The server device 100 overwrites the emergency key ID stored in advance in the storage unit 106 with the new emergency key ID received from the administrator terminal 200. In addition, the administrator changes the emergency authentication data stored in the electronic lock device installed in the managed property so as to correspond to the new emergency key ID. As a result, each time disaster information is received, the emergency key ID is updated, so that one emergency key ID can be prevented from being reused for one managed property, thereby improving security. it can.

  FIG. 5 is a block diagram illustrating the configuration of the mobile terminal. The mobile terminal 300 is a smartphone, for example. The mobile terminal 300 may be a wireless communication terminal such as a tablet terminal or a dedicated terminal as an electronic key terminal.

  The mobile terminal 300 includes, for example, a control unit 302 configured with a CPU, a network connection unit 304 serving as a network interface, and a communication unit 305 configured with an NFC interface based on short-range wireless communication. The control unit 302 includes a memory 303 composed of a nonvolatile memory such as a flash memory. In addition, the communication unit 305 may employ a communication standard other than NFC. For example, an infrared communication interface based on the Bluetooth (registered trademark) standard may be used. In addition to these, the mobile terminal 300 includes a display unit 306 configured with, for example, a liquid crystal display, for example, an operation unit 308 configured with a touch panel.

  Application software for performing a locking / unlocking operation by performing short-range wireless communication with the electronic lock device 400 is installed in the mobile terminal 300 in advance and stored in the memory 303. When the mobile terminal 300 receives an unlocking state signal indicating that unlocking described later has been executed from the electronic lock device 400 after executing the unlocking operation, the server device displays log information indicating that unlocking has been executed. To 100. Although details will be described later, the log information transmitted from the mobile terminal 300 to the server device 100 includes the mobile terminal identification ID and the unlock time information.

  FIG. 6 is a block diagram illustrating the configuration of the electronic lock device. The electronic lock device 400 includes a control unit 402 configured by, for example, a CPU, a storage unit 403 configured by, for example, a hard disk drive, and a communication unit 404 configured by, for example, an NFC interface by short-range wireless communication. Note that the communication unit 404 may employ a communication standard other than NFC. For example, an infrared communication interface based on the Bluetooth (registered trademark) standard may be used. In addition to these, the electronic lock device 400 includes a drive unit 406 configured by, for example, a solenoid, and a lock unit 408 configured by, for example, a dead bolt that is driven by the drive unit 406.

  The communication unit 404 is arranged at the door of the managed property. When the mobile terminal 300 comes close to the communication unit 404, the control unit 402 performs short-range wireless communication with the mobile terminal 300 via the communication unit 404 and reads the emergency key ID stored in the mobile terminal 300.

  The control unit 402 determines whether or not the emergency key ID read from the mobile terminal 300 matches emergency authentication data stored in advance in the storage unit 403. When determining that the emergency key ID matches the emergency authentication data, the control unit 402 drives the drive unit 406 to unlock the lock unit 408.

  The electronic lock device 400 is a device responsible for locking and unlocking a managed property that is a building related to a disaster. Therefore, it is desirable to provide a backup power source in addition to a normal household power source. For example, as a backup power source, a secondary battery or a solar power generator may be provided, or a power supply terminal for connecting an external power source may be provided. For example, a mobile battery that is also used for a smartphone, a portable generator that rotates a user's handle, and the like are connected to the power supply terminal. In addition, the electronic lock device 400 may receive power from a smartphone via a USB cable or the like, for example. If application software for power feeding is installed in the smartphone in advance, the electronic lock device 400 can receive power supply from the smartphone via the USB cable.

  FIG. 7 is a flowchart for explaining the operation of the electronic lock management system according to the first embodiment. Each column represents processing executed by the control unit 102 of the server device 100, the control unit 302 of the mobile terminal 300, and the control unit 402 of the electronic lock device 400 in order from the left side. Here, in the following description, the respective processes are simply expressed as “server device 100”, “mobile terminal 300”, “electronic lock device 400”, and the like.

  Note that the server device 100 according to the present embodiment manages a plurality of managed properties in each of a plurality of management areas. In this figure, the operation of the mobile terminal 300 registered in association with one managed property in one managed area is shown as a representative. The operation of the electronic lock device 400 installed in the managed property is shown as a representative.

  First, in step S101, the server apparatus 100 stores a registration list including managed area information, managed property information, and registered terminal information in the storage unit 106 (step S101). Then, the administrator stores the emergency key ID associated with the electronic lock device installed in each managed property in the storage unit 106. Further, the administrator sets emergency authentication data corresponding to the emergency key ID in the electronic lock device 400 (step S301). After completing the above introduction work, the electronic lock management system 10 shifts to a use state.

  The server apparatus 100 determines whether disaster information has been acquired from the outside (step S102). If it is determined that disaster information has not been acquired (NO in step S102), the server apparatus 100 waits until disaster information is input from the outside.

  If it is determined that the disaster information has been acquired (YES in step S102), the server apparatus 100 recognizes the disaster prediction area included in the acquired disaster information (step S103). Next, the server apparatus 100 determines whether or not the management area registered in the registration list is included in the disaster prediction area recognized in step S103 (step S104).

  If it is determined that the registered management area is not included in the authorized disaster prediction area (NO in step S104), the server apparatus 100 returns to step S102 and disaster information is input from the outside. Wait until. On the other hand, if it is determined that the registered management area is included in the recognized disaster prediction area (YES in step S104), the server apparatus 100 is a disaster that is a management area included in the damage prediction area. In the prediction management area, a position information request signal for requesting terminal position information is transmitted to the mobile terminals registered in the registration list (step S105).

  The mobile terminal 300 receives GPS signals transmitted from GPS satellites at predetermined time intervals. The mobile terminal 300 calculates and acquires GPS information, which is its own terminal location information, from the received GPS signal (step S201). When receiving the position information request signal transmitted from the server apparatus 100 in Step 105, the portable terminal 300 transmits a terminal position signal including its own identification ID information and terminal position information to the server apparatus 100.

  The server apparatus 100 determines whether or not there is a response from the portable terminal that has transmitted the position information request signal in step S105 (step S106). Specifically, server device 100 determines whether a terminal position signal has been received from the mobile terminal. If it is determined that there is no response (NO in step S106), the server apparatus 100 determines all terminals that have transmitted the location information request signal as targets for transmitting the emergency key ID (step S107).

  On the other hand, if it is determined in step S105 that there is a response from the portable terminal that has transmitted the position information request signal (YES in step S106), the server apparatus 100 determines the emergency key ID from the information included in the received terminal position signal. Is determined as a target mobile terminal (step S108). Specifically, as described with reference to FIG. 2, the server device 100 specifies the mobile terminal closest to the managed property from the managed property location information and the terminal location information included in the received terminal location signal. . Then, the server device 100 determines the identified mobile terminal as a target for transmitting the emergency key ID.

  Next, the server device 100 transmits the emergency key ID to the mobile terminal determined as the transmission target in step S107 or step S108 (step S109). Specifically, as described with reference to FIG. 2, the server device 100 transmits the emergency key ID by e-mail to the mail address of the target mobile terminal. In the present embodiment, an expiry date is set for the emergency key ID. The server apparatus 100 transmits an e-mail in which information on the expiry date of the emergency key ID is described in the text. Server device 100, for example, “The expiry date of emergency key ID is aaa year bb month cc day dd hour ee minutes.

  A registrant who owns the mobile terminal 300 inputs the availability of the response on the operation screen displayed on the display unit 306. Upon receiving an instruction that can be handled from the registrant, the control unit 302 transmits an unlock information request signal, which is a request signal for requesting unlock information, to the server apparatus 100. On the other hand, when receiving an instruction indicating that correspondence is not possible from the registrant, the control unit 302 does not transmit the unlock information request signal to the server device 100.

  In this embodiment, a determination part determines the portable terminal 300 as a target which transmits emergency key ID, when a state acquisition part receives the unlocking information request signal from the portable terminal 300. FIG. Then, the transmission unit transmits the emergency key ID to the mobile terminal 300. On the other hand, when the state acquisition unit does not receive the unlock information request signal from the mobile terminal 300, the determination unit excludes the mobile terminal 300 from the target for transmitting the emergency key ID.

  Further, if the registrant determines that it is not necessary to unlock the disaster prevention storage warehouse because the scale of damage is relatively small, the registrant may instruct the portable terminal to be incompatible. Thereby, the unlock information request signal is not transmitted to the server device 100 from the portable terminal. The server apparatus 100 does not transmit the emergency key ID to a mobile terminal that does not receive the unlock information request signal. If the unlock information request signal is not received from any portable terminal, the server device 100 does not transmit the emergency key ID to any portable terminal. Therefore, when all registrants determine that unlocking is unnecessary, the server apparatus 100 can avoid unnecessary emergency key ID transmission processing.

  In the present embodiment, when receiving the unlock information request signal from a plurality of mobile terminals, the server device 100 transmits the emergency key ID to the mobile terminal that has transmitted the unlock information request signal. However, the server device 100 may transmit the emergency key ID to the mobile terminal closest to the target disaster prevention storage warehouse when the unlock information request signal is received from a plurality of mobile terminals. In this case, the server apparatus 100 acquires each terminal position information of the portable terminal which has transmitted the unlock information request signal. And the server apparatus 100 specifies the portable terminal nearest to the target disaster prevention storage warehouse from the portable terminals which have transmitted the unlocking information request signal using the same method as the first embodiment, An emergency key ID may be transmitted.

  Moreover, after acquiring the terminal location information from all the mobile terminals associated with the target disaster prevention storage warehouse, the server apparatus 100 may inquire whether the mobile terminal is compatible in the order closest to the target disaster prevention storage warehouse. And when the unlocking information request signal is received from the inquired portable terminal, the server apparatus 100 may transmit the emergency key ID to the portable terminal.

  FIG. 9 is a flowchart for explaining the operation of the electronic lock management system according to the second embodiment. In addition, description is abbreviate | omitted about the process which overlaps with the flow which concerns on 1st Embodiment demonstrated using FIG.

  The processing up to step S104 is the same as the processing of the electronic lock management system 10 according to the first embodiment described with reference to FIG. When the server apparatus 100 determines that the management area registered in step S104 is included in the certified disaster prediction area (YES in step S104), all the mobile phones associated with the disaster prediction management area The terminal is inquired of whether or not the emergency storage warehouse can be unlocked (step S405). In the present embodiment, the server device 100 transmits a compatibility confirmation signal to the mobile terminal.

  When receiving the support availability confirmation signal from the server device 100, the mobile terminal 300 causes the display unit 306 to display an operation screen for controlling the support availability notification program as described with reference to FIG. Then, the portable terminal 300 determines whether or not the instruction from the registrant is a compatible instruction (step S501).

  If it is determined that the instruction from the registrant is a compatible instruction (YES in step S501), the portable terminal 300 requests unlocking information from the server device 100 (step S502). The terminal 300 transmits an unlock information request signal to the server device 100. On the other hand, when it is determined that the instruction from the registrant is not a response instruction (NO in step S501), the mobile terminal 300 continues to wait for reception of a response confirmation signal.

  In step S406, the server apparatus 100 determines whether or not there is a response from the portable terminal that has transmitted the response confirmation signal (step S406). If it is determined that there is a response from the mobile terminal that has transmitted the compatibility confirmation signal (YES in step S406), the server apparatus 100 identifies the mobile terminal that is the transmission source of the unlock information request signal (step S408). . Then, the server device 100 determines the identified mobile terminal as a target for transmitting the emergency key ID. The server apparatus 100 transmits the emergency key ID to the mobile terminal determined as the transmission target in step S408.

  On the other hand, when it is determined that there is no response from the portable terminal that has transmitted the response confirmation signal (NO in step S406), the server apparatus 100 continues to receive disaster information. In this case, the server apparatus 100 does not transmit the emergency key ID to any portable terminal.

  The mobile terminal 300 receives the emergency key ID from the server device 100 (step S503). Next, the portable terminal 300 shifts to step S204 and executes the subsequent processing.

  In the above description, the electronic lock management apparatus has been described using an example configured with one server. However, the electronic lock management apparatus may be composed of a plurality of servers, and each server may play a different role. For example, the server that acquires the disaster information and the server that transmits the unlock information to the mobile terminal 300 may be different from each other.

  In the above description, when the server apparatus 100 obtains an emergency signal such as an emergency earthquake bulletin transmitted from an administrative agency or a disaster occurrence notification signal from the administrator terminal 200, any of the registrants. Description has been made using an example in which unlocking information is transmitted to the mobile terminal 300. However, the server apparatus 100 may transmit unlock information to the mobile terminal 300 of any registrant when both the emergency signal and the disaster occurrence notification signal are acquired. The credibility of disaster information can be enhanced by using the reception of the two signals of the emergency signal and the disaster occurrence notification signal as a trigger for starting the unlocking information transmission operation. When the server device 100 acquires an emergency signal, the server device 100 transmits a signal notifying the administrator terminal 200 that the emergency signal has been acquired, and prompts the administrator to transmit a disaster occurrence notification signal. Good. In this case, the disaster occurrence notification signal has an implication as an approval signal that the administrator approves to transmit the unlocking information to the mobile terminal 300 of any registrant.

However, various buildings related to disasters can be managed properties. For example, the managed property may be a school gymnasium that serves as an evacuation site, or a gate of an evacuation route that goes up to a hill where entry is prohibited during normal times. And the server apparatus 100 may change the unlocking information transmitted to the registrant linked | related with each managed property according to the characteristic of the managed property. For example, when the managed property is a disaster prevention storage warehouse, it is preferably locked in order to prevent intrusion by a third party, except when taking out goods in an emergency. On the other hand, in the case of an evacuation facility or evacuation route gate, it is preferable that an evacuee can enter or pass through at any time in an emergency. For this reason, for example, when the managed property is a disaster prevention storage warehouse, the server apparatus 100 may transmit locking / unlocking information that can be locked and unlocked to the target mobile terminal. Further, when the managed property is an evacuation site, the server apparatus 100 may transmit unlocking information that allows only unlocking.

  In the above description, the electronic lock device 400 has been described using an example in which it is not connected to an external network. However, the electronic lock device 400 may be connected to an external network, and may be able to communicate with the server device 100 via the network. Thereby, the administrator can update the emergency authentication data of the electronic lock device 400 in accordance with the timing of updating the emergency key ID by remote operation from the administrator terminal 200 via the network.

  In the above description, a non-contact type electronic lock device has been described as an example of the electronic lock device 400. However, the electronic lock device 400 may be a contact-type electronic lock device that directly inputs authentication data using a numeric keypad, for example. In this case, the server apparatus 100 transmits authentication data information input to the numeric keypad to the mobile terminal of the target registrant instead of the emergency key ID.

  In the above description, the case where the lock installed in the management target is an electronic lock, but the lock is not limited to an electronic lock. For example, a lock or a safe lock that is unlocked using a physical key may be used. In the case of a lock that is unlocked using a physical key, the server device 100 transmits, as unlocking information related to unlocking, information on a key management location for unlocking the lock to the mobile terminal.
